Problem
1. Write a function that first increases the frequency of a sound by a factor of 3, and then decreases it by the same factor. Compare the original sound with the one the function returns in the explore view.
2. Write a function to input a sound, then create a canvas sound of the same length. Copy samples from the input into the canvas every other position, i.e., copy from index 0 in the input into the canvas at index 0, then copy from index 2 (skipping index 1) in the input into the canvas at index 1. What do you hear in the canvas sound? Same sound? Faster? Slower?
